In cryptography, a salt is random data that is used as an additional input to a one-way function that hashes a password or passphrase.This allows for later authentication while defending against compromise of the plaintext password, even in the event that the database is somehow compromised.

A cryptographic hash function is a hash function; that is, an algorithm that takes an arbitrary block of data and returns a fixed-size bit string, the (cryptographic) hash value, such that any (accidental or intentional) change to the data will (with very high probability) change the hash value.

Nevertheless, if you have concerns, you may use our app and all associated services except the eGDC-sync without divulging any sensitive information, if you wish.

In any case, the choice to use the sync service is optional and even without it, the CPD Pro app will bring you enormous benefits by letting you record your activity immediately and by keeping your CPD records secure in a single place.
